Flow control valve



United States Patent 3,034,530 FLOW CONTROL VALVE George A. Gerard, West Point Pleasant, NJ. (1014 Oak St., Roselle, NJ.) Filed Jan. 26, 1960, Ser. No. 4,752 4 Claims. (Cl. 137-532) The present invention relates to a flow control valve and it particularly relates to a flow control valve which may be associated with a heating system.

Although not restricted thereto, the present flow control valve is particularly designed to be used in combination with a hot fluid heating system.

It is among the objects of the present invention to present a simple, reliable valve construction for a heating system which is not subject to derangement, does not require any maintenance and which may be readily associated with a pumping mechanism to control the flow of hot liquid to or from a heating system.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects it has been found most satisfactory, according to the preferred embodiment of the present invention, to provide a cylindrical housing with a scalloped edge disk washer having in-turned elements which are designed to be seated against a peripheral annular valve face.

Desirably the valve disk is hinged'ly mounted on a weighted element so that it will be seated against the annular valve seat except when suflicient pressure is exerted thereagainst to unseat the same.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and mangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

FIG. 1 is a side elevational view, showing how the pump may be associated with a centrifugal pumping device.

FIG. 2 is an enlarged sectional view taken upon the line 22 of FIG. 1, upon an enlarged scale as compared to FIG. 1.

FIG. 3 is a transverse sectional view upon the line 3-3 of FIG. 2.

FIG. 4 is a transverse sectional view upon the line 4-4 of FIG. 2.

Referring to FIGS. 1 to 4, there is shown a motor A having a support structure B at the top of which is mounted the centrifugal pump C.

The centrifugal pump has an inlet duct D, a discharge duct E, and an outlet check valve F.

The present invention is particularly directed to the out let flow control check valve P, which is shown in detail in FIGS. 2, 3 and 4. The motor A, the frame B and the elements D and E, together with the centrifugal pumps C, may be of conventional construction and are not shown in detail.

As indicated in FIG. 2, the conduit E has the flanges 20 receiving the bolts 21.

The bolts 21 hold the annulus 23 against the flanges 20 with the gasket 22 forming a tight fit. The annulus 23 3,034,530 Patented May- 15, 1962 P ce receives the tube 24, which is soldered in position as indicated at 25.

This tube in turn is mounted by means of a soldered connection 26 to the annular valve seat 27. This annular valve seat 27 is mounted inside the cylindrical valve housing 28. The valve housing 28 terminates in the annulus 29, which carries the outlet flow to 30.

Pressed against the inside face 31 of the valve seat annulus 27 is the scalloped disk valve 32 having the scalloped openings 33.

Between the scalloped openings will be the legs 34, the edges of which are closely adjacent the internal diameter of the cylindrical valve housing 28 and the outer edge of the valve seat 27.

The valve plate or disk 32 is mounted by the central axial carrying rod 35, which is fixedly mounted at 36 in an opening 37 in the weight 38 (see FIGS. 2 and 3).

The cylindrical weight 38 in turn has an upstanding arm 39, in the end 40 of which is received the pivot rod 41.

The pivot rod 41 extends through the spacer sleeves 42 and at its ends 43 it is mounted in openings 44 in a liquid tight manner in the cylinder 28. p

To limit the movement of the scalloped disk valve 32 a series of inwardly directed pins 45 are shown positioned around the periphery of the cylinder 28 and extending inwardly. Four pins are illustrated but any number may be employed.

This valve is very reliable in construction and the scalloped plate 32, which may he of either brass or steel, for example A: inch thick and 1 inches in diameter, will give a quicker release, although it will give an adequate seal under the weight which holds it down when there is no pressure in the direction 47.

The valve plate 32 has its edges spaced sufliciently from the interior of the cylinder 28 to permit free movement against the pins 45 which are normally positioned much closer to the seated disk or plate 32 than shown in FIG. 2 where an expanded showing is illustrated.

It will be noted that the pivot 41 is positioned between the center of gravity of the weight 38 and the disk or plate 32.

It is only necessary for the disk or plate 32 to crack oil the annular seat 27 to permit flow in the direction 47 where the disk or plate 32 is sufiicient'ly thin to be flexible the pins 45 will also act as a stop.

The valve annulus 27, as well as the cylinder 28, may be of brass or still tubing. The scalloped edges permit an immediate relief as soon as the disk 32 is cracked oil the seat 27 The pins 45 will act as stop elements to limit the opening movement of the scalloped valve disk 32.

The weight 38 will hold the scalloped disk 32 firmly against the seat when there is no substantial pressure in the direction 47.

It is thus apparent that the applicant has provided a simple, inexpensive, reliable valve construction, particularly suitable for hot fluid systems where either hot oil or hot water may be utilized in such heating systems.

The valve will be self-cleaning and will not be subject to cocking oil the seat, and it will be reliable in operation. It makes an ideal flow control valve for hot water, hot oil or other hot liquid heating systems.

As many changes could be made in the above flow control valve, and many widely difierent embodiments of this invention could be made without departure from the scope of the claims, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.

Having now particularly described and ascertained the nature of the invention, and in what manner the same is to be performed, what is claimed is:
